**Trader consensus centers on 13°C as the day's minimum in Amsterdam, driven by converging numerical weather model outputs and real-time observations showing overnight cooling to around 13–14°C under northerly flow, persistent cloud cover, and light showers.** Current conditions feature temperatures declining through the evening to the low-to-mid teens Celsius, consistent with GFS and other guidance projecting a minimum near 13°C amid moderate humidity and dew points supporting limited radiational cooling. This aligns with typical late-August climatology for the region, where overnight lows often settle in the 12–15°C range. The 97.5% implied probability reflects strong model agreement and skin-in-the-game assessment of low uncertainty. Realistic challenges include unexpectedly clear skies accelerating cooling below 13°C or station-specific measurement variations at official sites, though such shifts appear unlikely given ongoing cloudiness.
